Okay, it wasn't a barn- it was in the storage area of a music store. Hi folks. I'm the guy who's been peeping in the window and putting my ear to the door for a few years now. I finally decided to knock- thanks for letting me in. So in the back of a small music store I help out at once in a while I saw what looked like a disassembled princeton reverby thing that somebody gave up on. It had 6 mismatched knobs over an all black spray-painted faceplate, a 12" speaker behind a crookedly applied silverface era grillcloth, a large one-piece back panel that was only open at the top for ventilation, and foam was stapled on every surface inside the cabinet. I'd always wanted a princeton reverby thing and enjoy projects so I contacted the owner of the amp and asked if they wanted to sell it (it had been sitting in the shop for several years) and offered a few hundred dollars. At first they declined but later accepted my offer so I bought the thing, brought it home and started digging. Removing all the foam and staples revealed the original "AA764" tube chart and a '65 date code. The transformers also dated to '65, and the chassis dated to early '66. Whoa. I checked all the small tubes in another amp and found a bad one. Reassembled the thing, threw in a good matched pair of JJ 6V6's, fired it up and guess what? It worked. EVERYTHING worked- volume, treble, bass, beautiful 3D reverb, deep tremolo. And it sounded amazing. The one thing I wasn't crazy about was the re-coned 12" Utah- so I threw in one of my original cone JBL K120's. Perfect. That was a couple of weeks ago. Since then I took it to an amp-savvy friend who checked voltages and said everything looked surprisingly good (the circuit appears to be original and un-molested). He recommended I install a grounded power cable (done), and replace the filter, bias, and coupling caps (should be here tomorrow). Which brings up the first of many questions I have about this amp- but I'll save it for now. Also since then I dangerously gigged with this amp- fifty-something year old caps and all, and it performed beautifully. That's all for now. Apologies for the long first post- I'll try to keep it short from here on out. And thanks again for letting me in.
